MANUFACTUREOF BUTTONS.

SPECIFICATION forming part of Letters Patent No. 380.807, dated April 10, 1888.

Application filed May 10, 1887. Serial No. 237,756. (No model.)

fo @ZZ zij/1,0m, it may concern:

Be it known that I, DANIEL A. LADD, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Buttons, of which the following-is a full, clear, and exact description.

My invention relates to an improvement in buttons, especially applicable to that class of buttons known as collar-buttons,77 and has Io for its object to reduce the oost of manufacture and produce a perfect and strong button more rapidly than has heretofore been accomplished.

The invention consists of the method of I5 making buttons, all as hereinafter fully described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate 2o corresponding parts in all the figures.

Figure 1 is a central vertical section t-hrough an unfinished shank. Fig. 2 is a central vertical section through a button in which the shank is complete and head uninished. Fig.

z5 3 is a central vertical section through a finished button. Eig. 4 is an elevation of the same. Fig. 5 is a central vertical section through a modification.

In carrying the invention into effect I first 3o make the shank A of the button, which is preferably made tubular and provided with a fiange, a, integral with the lower end, forming a base. To give rigidity andstrength to the said shank a wire, a', of suitable size is held suspended therein, as shown in Fig. 1, in any approved or suitable manner. Over the base or flange a the usual shoe,B,is clamped, which shoe is adapted to constitute the back of the button.

When the shank and back have been duly nished as adapted to be worn, I take a hollow spherical body, D, which has been previously properly finished, and provided with an aperture, d, in one side, which aperture is of a 4 5 size about equal to the diameter of the shank,

and into said aperture I place the upper end of the shank., as shown in Fig. 2. The shank and body are now placed between suitable dies and the body D compressed to form the head, the said compression causing the aper- 5o ture to become smaller and the head be held, thereby becoming substantially an integral portion of the shank by friction, as shown in Figs. 3 and 4.

It will readily be secu that when the head is compressed any desired form may be imparted thereto, and also that the base of the bottom, including the shoe, may likewise be given any suitable contour in the same operation.

It will of course be understood that insteadof inserting thepiece of wirein ahollow shank the shank might be formed solid, and that the body D need not be strictly spherical without departing from the spirit of my invention.

One great advantage of the button above described is that the parts may be completely inished before they are united, and another is that the manufacture of the article is greatly expeditedV by the simple process of lapping 7;) and forming.

If found desirable in practice, the body D may be so placed upon the shank as that when said body is compressed to form the head the shank will support the central portion, as 75 illustrated in Fig. 5.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

The method herein described of Inanufac- So turing buttons, consisting in Irst forming a shank and an approximately-spherical hollow and apertured body, then inserting the end of the shank in the aperture of the body, and finally compressing the body to the form ofthe head of a button, substantially as described, whereby the head will be rml y secured to the shank and provision made for giving form to the head and securing the same to the shank at one and the same operation, as set forth.
